a) \( a x+3 a+2 x+6 \) b) \( 2 x^{2}+4 x y-3 x y-6 y^{2} \) a) \( a^{3}-4 a^{2}-4 a+16 \)

Simplify the expression by following steps: - step0: Solution: \(ax+3a+2x+6\) Calculate or simplify the expression \( a^3 - 4*a^2 - 4*a + 16 \). Simplify the expression by following steps: - step0: Solution: \(a^{3}-4a^{2}-4a+16\) Calculate or simplify the expression \( 2*x^2 + 4*x*y - 3*x*y - 6*y^2 \). Simplify the expression by following steps: - step0: Solution: \(2x^{2}+4xy-3xy-6y^{2}\) - step1: Subtract the terms: \(2x^{2}+xy-6y^{2}\) Here are the simplified forms of the given expressions: a) For the expression \( a x + 3 a + 2 x + 6 \): - The simplified form is \( ax + 3a + 2x + 6 \). b) For the expression \( 2 x^{2} + 4 x y - 3 x y - 6 y^{2} \): - The simplified form is \( 2x^{2} + xy - 6y^{2} \). c) For the expression \( a^{3} - 4 a^{2} - 4 a + 16 \): - The expression remains as \( a^{3} - 4a^{2} - 4a + 16 \) since it cannot be simplified further.
